SP10 Mk II vs Mk III

I have never replaced the caps, when I got my first SP10 about 10-12 years ago, It was in a McCurdy Plinth with some strange broadcast arm. The strobe did not work on it, so I began a several year hunt for a strobe. I found one on Ebay (remember the good old days on Ebay?? 1997-8!!) You could find anything there!!I never did try to replace the bulb assembly, my tech did not want to open the SP10 up. I never imagined it was a problem in the Power supply. That SP10 got sent down the road as I jumped into some other mad Turntable project. It was not until the last two SP10s that I started to suspect it was some kind of Power supply issue. Somewhere in my basement is an SP10 strobe!?
Thanks Lewm, I will get that PS looked at this week. Is a schematic needed or is it pretty obvious/straight forward?

Schematic is available either from Vinyl Engine or from a pay site. (I can't remember where I got it.) If you're knowledgable, you may be able to read it yourself. I build tube stuff all the time, but I cannot make out what's going on in the SP10 schematic.

Does any one know of a good tech who can change out the capacitors since I wouldn't know a capacitor from a diode? Also, does anyone know of a tech comfortable with cleaning out and replacing the old bearing oil?

The SP10 MkII power supply has three voltages +5V, +32.5V and +140V. The 140V supply is used to power the strobe light. It is simple half wave rectifier circuit using a single diode, protected by a 315mA fuse - always check fuse F3 before anything else.

Microstrip.

The two voltages responsible for operation, +5 volt and +32.5 volt are the only important ones. The strobe is not necessary and most people agree it only adds noise.

I wonder if it would improve performance of MK2 if a tube circuit were designed to replace the stock Technics supply?
